Verify the power outlet is active.
Check if the power adapter is damaged.

Ensure your amplifier or active speakers are powered on and set to the correct input.
Adjust the volume on both the decoder and your audio system.
For digital inputs (Optical/Coaxial), ensure the source device is outputting PCM or a supported format (DTS, AC3). Some TVs may require setting the digital audio output to "PCM" or "Bitstream" instead of "Auto".
If using HDMI ARC, ensure ARC is enabled on both the TV and the decoder, and that the HDMI cable supports ARC.
